The following report documents an investigation of operational readiness OR rates performed by the Department of Systems Engineerings Operations Research Center ORCEN at the United States Military Academy during academic year 1997-1998. The report is organized into three major areas. The first area provides a historical review of the evolution of OR rates. In this section we determined how and why the current FMC standardsgoals are 90 for all equipment other than aircraft and 75 for aircraft. The second area of the report is an analysis of 24 months of OR reports for the M9 ACE, MIAl, and CH-47D. The objective of our data analysis was to understand what effect, if any, that several previously unconsidered variables have on a units ability to meet the current FMC goals. Through our historical review and data analysis, we identified an appropriate method to establish OR standards for reportable equipment. We recommend using a quality control paradigm to establish equipment serviceability standards based on the historical mean and subsequent levels defined by the number of standard deviations away from the mean. We propose that these standards should be established as a function of equipment type and the potential for deployment of the unit that the equipment is assigned. The third major area of the report provides an investigation of the current Equipment Serviceability ES evaluation system used in the Unit Status Report USR. We developed four potential alternative ES evaluation systems incorporating our proposed methodology for establishing ES standards. Finally, we identified the alternative system that best satisfies the objective of the ES evaluation system, which is to serve as an indicator of how well a unit is maintaining its on-hand equipment AR 220-1, Sep. 97, 6-1.
